There is no special limit. Specific examples of the photocatalyst material include titanium oxide, tin oxide, oxidized crane, iron oxide: zinc oxide, chromium oxide, oxidized ruthenium, oxidized nail, oxidized oxidized, oxidized f, oxidized, cerium oxide, cerium oxide, cerium oxide. , manganese oxide, oxidation, emulsified money: oxides such as nickel oxide, cerium oxide, oxide oxide, oxides of the plurality of metals, metal oxides doped with nitrogen or metal ions, and the like. Further, for example, a metal oxide such as a cocatalyst such as a metal or a metal salt or a photosensitizing dye may be carried on the surface. The cuprous oxide is not limited to a crystal structure or an amorphous material, and has a crystal structure regardless of its crystal structure, and is capable of exhibiting high antibacterial properties and antiviral properties. Therefore, the crystal structure of cuprous oxide and the like are particularly limited. The average particle size of cuprous oxide is preferably 〇 〇1~1〇. Further, ί describes the average particle diameter in #, and the meaning of the particle size distribution in the particle size distribution known by the laser diffraction or scattering method is 5% by volume.
